CATCH FOR PERFORATED BOARD ATTACHMENTS Filed Jan. 11, 1968 INVENTOR.

JAMES W. H INDLIEY United States Patent US. Cl. 248220.5 3 ClaimsABSTRACT OF THE DISCLOSURE A catch for perforated boards which willsecure attachments in place in the perforated board by holding a portionthereof in frictional contact with the perforated board.

BACKGROUND OF THE INVENTION There are available on the market a numberof attachments which are adapted to be inserted through holes that areprovided in a perforated board. The majority of these attachmentsutilize a single hole to support the same on the board, and in the pastit has been necessary to utilize clips or other similar devices thatwould stabilize the attachment in position on the board. The stabilizersof the prior art have consisted of wire formed into an expanding clipthat would penetrate an adjacent hole in the perforated board and thusstabilize the position of the attachment. These devices do not holdwell, are small and are thus apt to be lost. Various approaches to solvethis problem have been attempted as, for example, the form of a latchthat is shown in United States Patent No. 2,961,724. It is, however, notalways necessary to have a device which is sometimes known as astabilizing device in the form that will provide two-dimensionalstabilization. For the most part the prime requisite is to establishsingle dimensional stability and maintain the attachment device where aportion thereof will remain in the contiguous relationship with respectto the plane of the perforated board.

SUMMARY OF THE INVENTION A catch for a perforated support board which isprovided with an aperture for the reception of the offset hook portionof an attachment device for the perforated board and which has a catchmeans associated therewith that will grip a portion of the shank of theattachment wherein the portion of the catch surrounding the aperture forthe reception of the offset hook portion is of substantial area and isformed as an arcuate spring plate so that substantial surface engagementwith the surface of the perforated board is provided.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of theinvention in position with a perforated board attachment;

FIG. 2 is a side elevation of the invention as illustrated in FIG. 1with the perforated board shown in section;

FIG. 3 is a bottom view looking substantially from the lines 3-3 of FIG.2 with the perforated board shown in section;

FIG. 4 is a view similar to FIG. 2 illustrating the manner in which thecatch of the instant invention is used; and

FIG. 5 is a section on line 5-5 of FIG. 2.

3,4l7-7677 Patented Nov. 11, 1969 'ice DESCRIPTION or THE PREFERREDEMBODIMENT The catch of the instant invention is adapted for use with ausual perforated board 10 which consists of a plurality of perforations11 formed therein which perforatiorifs sometimes assume a variety ofspacings depending upon the source of manufacture of the perforatedboard. Attachments have been devised for use with a perforated board tofacilitate the storage and/or hanging of articles thereon, and such anattachment 12 is illustrated as comprising a shank portion 13 with anoffset hook or board engagement portion 14 and an article suspendingportion 15.

The catch generally designated 17 may be formed from resilient sheetmetal and comprises a plate-like portion 18 which is arched as at 19 andis then provided with a surface engaging end portion 20 that is bentoutwardly at the. upper terminus thereof. The plate-like portion 18 hasan aperture 22 through which the offset portion 14 of the attachment 12may pass, and the lower portion of the plate-like portion 18 is providedwith a pair of resilient arms 24 that are bent up out of the plane ofthe plate 18 in spaced relationship to form a gripping means for theshank 13 of the attachment 12. As shown more particularly in FIG. 5, thearms 24 are arcuately bent out of the flat plane of the plate 18 andthen reversely bent in an arc toform a restricted entrance portion as at25 spaced a distance less than the diameter of the shank 13 withoutwardly flared guiding lips for moving the arms apart as the shank 13is forced between them. These arms have sufficient resilience to springback toward each other and grip the shank between them.

The catch is applied to the attachment 12 by inserting the offset hookportion 14 through the aperture 22, and then the offset hook portion isinserted into one of the holes 11 in the perforated board (see FIG. 4),and when in the position as illustrated in FIG. 4, the shank 13 ispressed toward the board and into engagement with the spaced arms 24 sothat the arms 24 resiliently grasp the shank 13 and force it intoengagement with the plate 18. In the engaged position as shown in FIGS.1-3, an extremely tight grip about the shank 13 is formed by the arms 24causing the lower portion of the plate 18 and shank 13 to act as onepiece, and thus the bent arc of the plate 18 would be as seen in dottedlines in FIG. 2 at 30. However, a spring pressure is developed byengagement of the upper end 20 with the board through the arched portion19 so that the arched portion is compressed slightly and pressure isapplied as at the upturned end portion 20 which will tend to swing theattachment about point 31 as a pivot, thus applying pressure at thelocation below this point 31 at both 32 and 33 or at one of theselocations which contacts first. In this fashion some resistance againstrotative movement of the attachment 12 is provided as well as completeorientation of the attachment in contiguous relationship with the board,the shank 13 being tightly held thereagainst as, for example, along therearward portion thereof.

I claim:

1. A catch for use with attachments of the type provided for perforatedboards comprising an elongated platelike portion arched in the directionof its length and having an aperture in said arched portion and meansadjacent one end of the arched portion to grasp an elongated portion ofthe attachment extending lengthwise of the plate 3 and hold theattachment in adjacent relationship with the perforated board.

2. A catch as in claim 1 wherein the means comprised spaced armsnormally spaced a distance less than the attachment so as to grip theattachment when inserted between them.

3. A catch as in claim 1 wherein said aperture is in the arched portion.
